"Foliar fertilisers are vital supplents to standard plant nutrition
found in the soil. Even if all elements are present in suffient
quantities the roots may still be unable to absorb them. For instance
during cold spring, or with high soil Ph. If this is the case then
Travena Foliar Feed is the answer for you."
